Hello Everyboby, 
 
My issue is below, 
 
I have 10 Meraki Access points that had worked correctely since 2 years ( i have license 3-years term). 
 
Now i have only 9  which work  and the 10th AP is " Unreachable for 14 jours"
 
* The network configuration is correct and it is the same for all AP ( the same network)
 
* When i check the DHCP Server i can see that the getted  a valid and reserved IP Address 
 
*   When  i  do the ping command it doesn't respond  [all network configurations is correct] 
 
* When i  check the cdp neighbor i can see the following : 
 
 
Device ID: xxxxxxxxxxxx [i cached it]
Entry address(es):
IP address: x.x.x.x [ the correct and intented reserved IP Adress]

* I try to mark the device as eligible for remplacement, but i get the folling returned message : 
 
" You don't have any devices in your organisation that are a part of a hardware remplacement program"
 
* Also, when i view the access ponts, this AP appear with red color and it state isn't as any cases state : 
 
offline  = 0 , alerting = 0 online = 9 , repeater = 0
 
*** Can somesone already had this problem or could guide me to resolve this problm?
